Sometimes we have to write 'backwards' to improve legibility. Odd though that may sound. Some languages are written from left to right. Some from right to left. And some ancient writing alternates, line to line. https://en.wikipedia.org/wiki/Right-to-left https://www.andiamo.co.uk/resources/right-left-languages https://en.wikipedia.org/wiki/Boustrophedon Users of modern rendering systems, such as in modern browsers, don't have to worry about this. This is because the renderer will handle LTR and RTL switches based on the language attribute. (Alway, text should be encoded in reading order.) But those implementing a bidectional rendering system might have to worry about such things. So what does that have to do with us, Python developers and users. According to the web: Arabic, Hebrew, Persian, and Urdu are the most widespread RTL writing systems in modern times. To provide legible localised (translated) help messages at the interactive Python interpreter, the system somewhere will have to correctly reverse Unicode strings, either before or after processing combining characters. There are about 422 million Arabic speakers, 110 million Persian, 5 million Hebrew and 100 million Urdu. Definitely worth doing, in my opinion. Otherwise the help message will look TO THEM like this: daer ot drah yrev si siht instead of this is very hard to read -- Jonathan _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
